Rs been a great car and I love it! I have an issue, when I'm in high rpms I hear it sucking air is the way it sounds to me but it's pretty loud. I'm not sure what it is or could be? Neve did it before until today and it's like a shhhhhhhh while in boost.

After I went stage 1 on stock intercooler, the IC to throttle body hose got kinked and started making a whooshing/vacuum noise at peak boost and let off towards redline. Apparently its a common issue in 08+ WRXs.

pretty much this. OP you can fix it yourself or just take it to the dealer. my guess is the dealer will not remove those "rubber endcaps" in the hose, so its just gonna happen again..
